Dr. When I was a child of about 10 years, I would climb a pole with my arms, and my body would stiffen, and would have an orgasmic happening, felt good. Eventually It was accompanied by ejaculation. Thought I broke something. Eventually I realized what it was. Could do this even as an adult. In high school gym class, would be asked to do pull ups on a bar. I always declined, knowing what the result would be. Would like to know if this is a common affliction in many men.
